- In Italy July 18, 1930 15 m (01. nz-es) The object of my invention is a machine adapted to execute, besides the ordinary chain stitch, other stitches particularly suited for producing cmbroideries imitatinghand made embroidery 5 (flat stitch, Hungarian stitch, running stitch, back stitch, point lance, etc.) as well as new stitches of colour shading and dotting effects.

: The machine according to my invention is advantageously of the type in which the chain 1 stitch is obtained by means of a hooked needle,

and a crank serves to direct the fabric in any desired direction under the presser foot of the machine. This type of needle is preferred because it makes it possible to use a great number of threads of various weights and grades that would hardly be workable with the usual sewingmachine type needles. However, the same advantageous results can be obtained with a machine fitted with ordinary needles and shuttles.

The chief characteristic of my invention consists in that stitches of various lengths can be obtained with my machine, while the fabric is always given. a feed that corresponds to the length of a normal stitch. This result is ob-' tained by employing at least two threads which work successively either according to a predetermined order, or at will. Of these two threads ,that which remains at rest is caused to extend under'the fabric (which will therefore be placed upside down on the machine) over a lengthcor- ,responding to the sum of the lengths of the normal stitches made by the thread at work.

This system of forming the stitches aifords several advantages. As the long stitches are obtained with a feed of normal length of the fabric, both the embroidering of any design, even in its smallest details, and the use of fabrics which would gather into folds if subjected to a feed corresponding to a long stitch, are considerably 4,0 facilitated. The long stitch being made under the fabric tobe embroidered, it'is easier to follow the design and the stitches cannot be picked up by the foot of the machine, so that the embroidery thus obtained is perfect.

4s A manually operated device enables the worker to diminish at will the length of feed of the fabric, or even to reduce it to zero, while the machine is working, so that the stitch can be ended exactly at the edge of the design before starting the return movement of the work.

7 A device is also provided to automatically vary the length of feed according to the nature of the materials that are cooperating with the needle.

According to my invention, a device, fitted to the machine, and controlled with the knee, as

hereinafter described, allows the operator to obtain stitches of any desired length, so that it be comes possible to flll up a pattern from one end to the other, thus imitating the "point lanc.

The thread distributorsare actuated by a single 5 cam, which can be easily and rapidly exchanged and the profile of which determines the type of stitch executed by the machine.

A release device, which throws the cam out of action, allows the machine to execute the normal 10 chain stitch.

In this manner, all kinds of stitches may be obtained: ordinary hand stitches may be imitated, or new stitches may be created, and this simply by changing the cam or by making use of 1 threads of various thicknesses and colours.

A stitch imitating the point lanc" may be obtained by intertwining two threads, of which one, for example, is of silk, and the other of line cotton. The silk thread will remain at rest, while 20 three normal stitches are being made with-the cotton thread, and the silk thread therefore ex-- tends on the under side of the fabric over a length corresponding to four normal stitches. By intertwining three threads, two of which form long 25 and alternate stitches, while the third forms short stitches which remain hidden under the former ones, thus forming a kind of stufling or padding,

it is possible to obtain a supple stitch in relief,

which, if made by'hand, would require going so twice over the work, and even then would not have the same precision as when obtained with my machine. g

' By intertwining three cotton threads of different shades, embroideries"areobtained which dis- :35

play beautiful combinations of colors and give the I illusion of changing color. I

Furthermore, the automatic device for controlling the feed can also contribute in increasing the-relief effect already obtained.

Preferred embodiments of my invention as applied to machines of a known type will be hereinafter described with reference to the accompanying drawings, given merely by way of example.

In Figs. 1, 2 and 6, the table or work plate I of the machine is provided on its under side with the organs for transmitting the movement to the thread distributor. 2 designates the usual shaft to which a rectilinear alternating motion is imparted at one of its ends through a bell-crank on the line lever carried by support 3. Shaft 2 is provided at its other end with an endless screw 4 meshing with a gear 5 and which playsthe part of a rack adapted to rotate said gear 5 in an oscillatory manner when shaft 2 moves with said rectilinear reciprocating movement. Shaft 2 may also be given a rotary motion about its own axis by means of a slotted sleeve 6 in which it is slidably keyed and of two couples of bevel gear wheels 1 and I which are controlled through the directing crank handle 8 (which also controls the clutch) carried by support 9.

It will be noted that shaft 2 of the machine according to my invention is not in the position which it usually occupies in ordinary machines, since gear 45 does notdirectly control the distributor under the needle plate. Gear 5 is journalled in a suppor l5 which is itself pivoted at its lower end in cross piece l8 secured to the under face of table I (Fig. '7). Said gear 5 drives an eccentric l0 (Fig. 5) which is integral therewith and over which is slipped the strap of connecting rod II. A guide l3, pivoted at H to support I5 is adapted to slidein a slot provided in connecting rod II. The free end of connecting rod II is ring-shaped and a member I] is fixed thereto which carries the three small thread distributing tubes I8, I80, lib of the distributor. (Fig. 5.) It will readily be understood that the normal oscillatory movement of support II for causing the thread distributing tubes to cooperate with the needle is imparted to said support by shaft 2 through gears 4 and 5, eccentric l0 and connecting rod ll. two lugs l9 and I3 to which are fixed springs 20 and 20', Fig. 6, which tend to rotate the support about its axis in such manner that tube l8b may be brought under the needle plate. One end of a small connecting rod 22 of adjustable length is connected-to another lug 2| projecting from a The other end of said connecting rod 22 is pivoted to crank 23 keyed to one ,end of shaft 24 which rotates in bearings 25 and 26. The first of said bearings is provided in cross piece l6 and the'other one is secured to table .I. To the otherend of shaft 24 is secured arm 21 which carries a roller 28 which is kept constantly in contact with the external surface of cam 29 (Fig. 1) by the action of springs 20 and 20. Thus cam 29 controls, through arm 21, shaft 24 and connecting rod 22, the angular position of support IS with respect to its support l6, and therefore the positionof pivot I4 and the initial positionof support II with respect to the needle. The outline of said cam29 is so chosen as to bring into operative position at the desired time one or the other of the thread distributing tubes l9, lBa

and llb. 1 e

Cam 23 is fixed by means of milled wheel 30 (Fig.2) on a shaft 3| which carries toothed wheel 32, in mesh with toothed wheel 33 which is Toothed wheel 33 is in mesh different threads, and that cam 29 has the outline shown in Fig. 3, that is to say an outline corresponding to the type of stitch illustrated in Figs. 20 and 21, the operation of the machine is as follows: I

The ends of three threads of the desired material and colour are engaged into the tubes 18, Mia and I8!) respectively,'said threads coming from three spools mounted'on a common support fixed to the table. When the machine is started, there takes place, besides the usual movements that take place in other machines of that type adapted to execute a chain stitch, an oscillatory movement of support I! caused by the movement of small connecting rod ll, actuated as above indicated byendless screw 4 meshing,

Support I! is provided withwith vertical gear 5 which is integral with 'eccenpart of the cam 29 designated by A, tube I8b cooperates with the needle. When the roller comes to run on the part of the cam designated by B, it causes shaft 24. to rotate about its own axis, and consequently the pivot I I of connecting rod II will be displaced with respect to table I, so that support U will be caused to bring tube I8a into the position previously occupied by tube I81), and the thread carried by said tube I8a will now be brought into action and will make a stitch.

As the cam further rotates and roller 28 comes in contact with part C of the cam, tube I8 and the corresponding thread will nowbe brought into operative position. The part of the outline of the cam designated by B and identical to B will now become operative and the machine will again make a stitch with the thread. carried by tube I8a. i

. From this moment, the part A of the profile of the cam comes again into action and a new cycle identical with the one above described is recommenced. While. one of the threads is working, the other two extend under the fabric which is being embroidered, so that, for example, in the case above described, while the stitch is first executed with the thread I8a, then with thread I8, then again with stitch Illa, the thread issuing from tube IBb stretches out underneath the fabric, so as to form a stitch having a length equal to that of four normal stitches. The same is true of the thread issuing from tube I8, whereas the stitch made by the thread issuing'from the tube I8a will have onlya length equal to that of two normal stitches.

In order to better illustrate the operation of the machine, I have shown in Figs. 24 to 31 an example that corresponds to the utilization of three threads I8, I and 80 of different colours. For instance thread I8 is red, thread I9 is white, and thread 80 is blue. r

The three thread distributing tubes I8, I8a and IN), which correspond to threads 80, I9 and 18 respectively arecarrled by a support II, which tube I8b describes a curve that closely surrounds the vertical axis of needle n, However, it is possible, through suitable means, to modify theinitial position of support I1 with respect to table I so that it is the curve described by tube I 8a (or by tube I8) that'closely surrounds the vertical axis of needle n.

Needle n is given a reciprocating vertical motion through a mechanism of a well known type. Table I is provided with a hole Ia so that needle n may pass through fabric 11, which is stretched on table I, and pick up the threads from the distributor.

In the position shown in Figs. 24 and 28, needle n is at the bottom of its vertical stroke and the portion thereof that islocated above fabric 11 is engaged in a loop of thread 80 formed by the preceding stroke of the needle. Thethread distributing tubes I8, I81; and I0b are located behind the vertical plane X-'-X (Fig. 28) passing through the vertical axis of needle n.

' Support I1 is then given a horizontal 'movement so that tube I8b moves along a curved line such asthat. shown by arrow F1 of Fig. 28.

Tubes I8, um a I0b are thus brought into the position shown by Figs. 25 and 29, so that thread 7 I8 is brought against needle M and is caught in the hooked part thereof.

Needle 11. now moves in an upward direction so that its point passes on the other side of the fabric 11, drawing thread I8 together with it, as shown in Figs. 26 and 30. Simultaneously, support II has been given a horizontal displacement in the direction of arrow F: of Fig. 29, so as to be brought into the position of Fig. 30..

Support" then completes its return movement in the direction of arrow F: of Fig. 30, so that tubes I8, I8a and lab are brought back into their initial position with respect to table I, as shown in Fig. 31. Simultaneously fabric 11 has been given a forward displacement toward the right hand side of Fig. 27, so that a loop is formed by thread I8, and the parts are ready for a new cycle of operations that will produce another stitch. The presser foot 45 that produces that displacement of fabric 11 has not been shown in Figs. 24 to 31 for the sake of clearness. Besides, the operation of said presser foot is well known in the art.

As above stated, the initial position of support I! with respect to table I can be changed through any suitable device so that tube I8a and thread I9 (or tube I8 and thread 80) will be brought into operative position with respect to needle n and will occupy the successive positions that have been shown and described for tube I81: and

thread 78. i

It will readily be understood that the threads that remain at rest, that is the threadsthat are not picked up by the needle, (threads I9 and 80 in the cycle of operations shown in Figs. 24 to 31) are merely caused, by each forward movement of the fabric, to extend on the face. of the fabric that is in contact with table I alonga length corresponding to one stitch.

,For instance, in the example shown in Figs. 24 to31 (in which support I1 is displaced in such manner that each of the thread distributing tubes I8, I 8a and I8b is successively brought into operative position with respectto needle n) each of the threads I8, 19 and 80 extends along a length corresponding to the stitch made with itself and to the stitches made withthe two otherv threads, that is along a length corresponding to three normal stitches. I

Figs. 22 and 23 show a machine provided with a device for controlling cam 29 which includes a change speed arrangement. The purpose of that arrangement is to allow for replacing a given cam 29 by another cam requiring a different speed of revolution with respect to the main shaft of the machine. Experience has taught that'it may be advantageous to obtain a rotation of the shaft 3| off-cam 29 equal to one fourth or one sixth of the rotation of the main shaft .of the machine, while leaving the cam thus driven in ,a predetermined relation with respect to the A sliding dog I04, slidably keyed on shaft I00,

is provided with projectionsadapted to engage on corresponding projections I09 or III] rigidly fixed to pinions I05 and I0! respectively, these pinions being loose on shaft I00. It will be understood that when the projections of sliding dog I04 are engaged on projections IIO, the movement of shaft I is imparted through pinions I01 and I08 to shaft 3|. On the contrary, whenthe projections of dog I04 are engaged on projections I 09 of pinion I05, the movement of shaft I00 is communicated to shaftll through pinions I05 and I06, and therefore with a different ratio.

The positions of projections I09 and H0 are so arranged as to keep cam 29 in proper relative angular position with respect to the other parts of the machine. y

The displacement of sliding dog I04 is controlled through a lever III (Fig. 22) provided with a milled knob II2 (Fig. 23). Lever III can be locked in any of three different positions by means of a spring pressed latch (not visible in the view of Fig. 23) cooperating with'frame 2I2 and moved by means of knob II2.

Figs. 1 and 4 show the hand operated device which makes it possible to diminish or even, if desired, to reduce to zero the feed movement of the fabric to be embroidered, while the machine is working. That device essentially comprises a support 4I fixed to the upper part of the head of the machine and to which arm 43 is pivoted at 42. Saidarm 43 is always kept in contact, by means of spring 44, with the upper end of rod 45 which controls,, through its reciprocating movement and in the usual manner, the displacement of foot 46. To support 4| is also pivoted at 41 the bell crank lever 40, which carries pivot 49 to which is keyed the end of lever 50, and to which is fixed the extremity of spring 5 I. when lever 50 is pushed forward with respect to the operator, so as to occupy position 50', shown in dotted lines, lever 48 rotates about pivot 41 until it comes into position 40, in which it prevents arm 43 and consequently rod 45 from moving upwardly, so that presser foot 48 no longer moves, and the fabric is not displaced.

Figs. 22, 22a and 23 show a device for automatically controlling the'lengthof feed of the fabric by the machine, said device being useful for the good formation of the stitch, when several materials are used simultaneously, some of these materials requiring a greater length of feed than the others.

The principle of that device consists in directly controlling the movement of the sliding piece I15 of the machine, which acts in the known manner upon the presser foot or the equivalent, through a cam IIG keyed on shaft 3| and comprising as many active sections as cam 29. Said cam acts on sliding piece II5 through roller HM and lever III which controls the rotary movement of shaft II8. On the other hand a lever H0 is keyed on shaft H8, which lever acts upon one extremity of lever I20, adapted to pivot about axis HI and the other end of which cooperates with projection II5a of the usual sliding piece II5. Owing to a piece I22 adapted to slide'in grooves provided in levers H9 and I20, and adjustably secured therein by means of a milled knob, it is possible to adjust the intensity of the action of the cam upon the length of the stitch.

The, operation of that device is as follows: Under the action of the well known spring I23, piece H5 tends to remain in its highest position, which results in roller I IBa being applied against cam H0 at A. When passing over portion B of cam II6, roller II8a is moved toward the right (Fig. 22), the left hand end of lever I20 is raised, which causes link H5 to move downward a distance equal to diflerence Rr, R being the disoutline, by displacing support 0|.

tance from B to the center 0 of the cam, and, r being'the distance from A to center 0 of said cam.

The length of feed of the machine is equal, or rather proportional to Rr. Then, when the stitch has been made, the roller moves along portion 'A' and then I along portion B of the periphery of the cam, causing the formation of a stitch proportional to length R'r, and so on. the coeflicient of proportionality being adjusted by acting upon the position of piece I22.

When it is desired to obtain stitches of any desired length, for instance when his desired to to the other one. use may be made shown in Figs. and 9.

An arm 52 is keyed in the proper position on shaft 24. Said arm 52 carries at its extremity a roller 53 against which bears a cam.54 keyed on shaft 55, which is journalled in supports 00 and 55 secured to table I of the machine. An arm 51 is also keyed on shaft 55, which arm extends vertically in a downward direction and is provided at its lower end with a plate 58 against which the operators knee can be brought to press. A spring 59 maintains arm 01 in the vertical position. On shaft 3|, there is keyed, instead of cam 29, a disk which constantly maintains tube I 8b in the operative position. When arm 51 is dis" placed by the knee bringing it into position 51 shown in dotted lines in Fig. 9, the projecting part of cam 04 engages roller 53 of arm 02 and pushes it in a downward direction, thusbringing it into position 52'. Shaft 24 is thus caused to rotate through the necessary angle for imparting such a displacement to support I! that said support brings tube Ila into the active position and thus causesthe thread passing through said tube Ilia to cooperate with the needle.

of the device till up the design of an embroidery from one edge Fig. 11 shows in a diagrammatic manner an of its v Fig. 12 shows in a diagrammatical manner another embodiment in which use is made, instead of a hooked needle, of a needle of the type used in the ordinary sewing machines. In that case, the thread must be contained in shuttles which must be brought under the needle in an order corresponding to the kind of stitch to be made. Shuttles 6866u66b are mounted in a support 61 adapted to rotate'about pivot 68. A toothed sector 69, also pivoted at 68 and receiving an alternating movement from shaft 2, keeps the shuttles rotating, while rod 22, jointed at one end to support 61 and at the other end to crank 23 (Fig. 6), shaft 24, arm 21 and cam 28, imparts to support 61 the necessary displacements for bringing the shuttles to their operative position in the desired order. Of course in this case instead of obtaining a chain stitch, I obtain a lock stitch, and there is a single needle thread, which interlocks in the fabric with the various shuttle threads. I

Fig. 13 shows, also in a diagrammatic manner, anotherenibodiment applicable to machines proplurality of 2. An embroidery machine of the type dey screw actuates 'gearj5 mounted vertically on support directly under the needle plate. On

the upperpart of gear 5, pivot 13 is eccentrically mounted, which pivot engages hollow cylinder 12 which carries distributingtubes lfl fatit's upperv part. Cylinder 12' is adapted to oscillate with respect to a fork' I I, which is in turn pivoted to the end of lever 10. Said lever '10 is keyedon shaft 24, which rotates in bearings' 'fi and 26 and is actuated, as above explained, through arm 21, roller .28 -and cam 29. It will be readily understood that the reciprocating rotary motion of gear 5 causes cylinder '13, and accordingly the tubes carried by it, to move with a reciprocating rotary motion about theaxis of the. needle and the transversal displacementstransmitted to the cylinder through the above described other organs connected to arm 10 bring the tubes in their operative position in a predetermined order, according to the kind of stitch to be obtained.

The machine according to my invention makes it possible to obtain many diiferent stitches of various kinds. By way of example, I have diagrammaticallyshown in .Figs. .14;=to 21 of the accompanying drawings four difierent stitches. The first one is shown in elevational view in Fig.

i 14, (the fabric being supposed ;tobe sectioned) and in plan yiew in Fig. 15.

That stitch imitates the running stitch and is formed by the intertwisting of only twothreads. The, fabric is shown at 11, and the two threads at I8, 19. The thread" is the only one to be visible; while thread 19 only serves to fix thread 18 and will therefore be of fine cotton and of the same colour as the fabric, so as to be mixed up with the latter and to cause only thread 18 to be seen. Thread 18 remains at rest during three stitches which are made by thread 19 and remain hidden under thread 18, which thus gives stitches having a length equal to that of four normal stitches.

Figs. 16 and 17 show inelevational view and in plan view respectively a running stitch combined with a back stitch. In this case, both thread 18 and thread 19 remain visible, and the effect is obtained by causing two stitches of each thread to alternate with two stitches of the other thread.

Figs. 18 and 19 show a stitch obtained by the intertwining of three threads 18-19-80, working in this order: -80-19-18.

Finally Figs. 20 and 21 show a stitch obtained by the intertwining of three threads and imitating the Hungarian point. Threads '18 and 19 form long alternate stitches, while thread 80, forms short stitches. For obtaining that effect, the threads work in the order: 18-80-1940.

While I have disclosed" what I deem to be preferred embodiments of my invention, it should be well understood that I do not wish to be limited thereto as there might be changes made in the arrangement, disposition and form of the parts without departing from the principle of,
